Merge tag 'docs-5.5a' of git://git.lwn.net/linux

Pull Documentation updates from Jonathan Corbet:
 "Here are the main documentation changes for 5.5:

   - Various kerneldoc script enhancements.

   - More RST conversions; those are slowing down as we run out of
     things to convert, but we're a ways from done still.

   - Dan's "maintainer profile entry" work landed at last. Now we just
     need to get maintainers to fill in the profiles...

   - A reworking of the parallel build setup to work better with a
     variety of systems (and to not take over huge systems entirely in
     particular).

   - The MAINTAINERS file is now converted to RST during the build.
     Hopefully nobody ever tries to print this thing, or they will need
     to load a lot of paper.

   - A script and documentation making it easy for maintainers to add
     Link: tags at commit time.

  Also included is the removal of a bunch of spurious CR characters"

   Filter is defined with two configuration parts:
   --AXI_ID defines AxID matching value.
   --AXI_MASKING defines which bits of AxID are meaningful for the matching.
-        0：corresponding bit is masked.
-        1: corresponding bit is not masked, i.e. used to do the matching.

   AXI_ID and AXI_MASKING are mapped on DPCR1 register in performance counter.
   When non-masked bits are matching corresponding AXI_ID bits then counter is
   incremented. Perf counter is incremented if
-          AxID && AXI_MASKING == AXI_ID && AXI_MASKING

   event at the same time as this filter is shared between counters.
